Answer:
y = 5x - 800
Step-by-step explanation:
If x represents the number of pages typed, 5x will represent how much money he earns from typing them, since he gets $5 per page.
Then, 800 needs to be subtracted from this because he spent $800 on the computer.
So, the equation will be y = 5x - 800 to represent his profit.

(a) Calculate the proportion of Juniors that are (1) currently working, (2) not working but have
had a job, and (3) never had a job.
Answer:
Juniors Currently Working: 14/51 = 0.27; Not Working but Have Had a Job: 22/51 = 0.43; Never Had a Job: 15/51 = 0.29.
Seniors Currently Working: 30/80 = 0.38; Not Working but Have Had a Job: 40/80 = 0.5; Never Had a Job: 10//80 = 0.13.
There is an association between employment status and grade level. Depending on whether the student is a senior or junior impact the likelihood of their employment status. For instance, more seniors are likely to be currently working than juniors.

Answer:
x = (3√2)/2
Step-by-step explanation:
In the isosceles right triangle the side lengths have the ratio ...
1 : 1 : √2
This means the short leg (x) is 1/√2 times the length of the hypotenuse. You want the ratio with a rational denominator, so you need to multiply numerator and denominator by √2.
[tex]x=3\cdot\dfrac{1}{\sqrt{2}}=3\cdot\dfrac{\sqrt{2}}{(\sqrt{2})^2}\\\\\boxed{x=\dfrac{3}{2}\sqrt{2}}[/tex]

CA+AB=CB
Step-by-step explanation:
CA + AB = CB
The lines CA and AB will sum up to CB.
What are collinear points?Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry.
Given here: CA and AB along the same line CB also A,B,C are collinear also ∠DAB+∠CAD=180 as they are adjacent angles and thus are supplementary. Therefore CA+AB=CB
Hence, The lines CA and AB will sum up to CB.

Hi please help me solve this the topic is on circle geometry, whoever answers will be marked as the brainiest.
=====================================================
Explanation:
Line PR is tangent to the circle at point T. Angle PTO is 90 degrees because of this.
Angle TON is 124 degrees. Triangle TON is isosceles (since we have two sides of the triangle TO and ON equal to the radius). Therefore angles OTN and ONT are equal base angles. Call these x for now
-------
Since 3 angles of any triangle always add to 180, we can say...
x+x+124 = 180
2x+124 = 180
2x = 180-124
2x = 56
x = 28
Therefore,
angle PTN = (angle PTO) + (angle OTN)
angle PTN = 90 + 28
angle PTN = 118

Generate a plan and describe the steps needed to solve the equation. 34 = –(m + 3)
Answer:
m=−37
Step-by-step explanation:
34 = -3 + -1m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add 'm' to each side of the equation.
34 + m = -3 + -1m + m
Combine like terms: -1m + m = 0
34 + m = -3 + 0
34 + m = -3
Add '-34' to each side of the equation.
34 + -34 + m = -3 + -34
Combine like terms: 34 + -34 = 0
0 + m = -3 + -34
m = -3 + -34
Combine like terms: -3 + -34 = -37
m = -37

[tex]h(x) = {2}^{x} [/tex]To solve the equation we must first find h-¹(x)
To find h-¹(x) equate h(x) to y
That's
[tex]y = {2}^{x} [/tex]Next interchange the terms
x becomes y and y becomes x
That's
[tex] {2}^{y} = x[/tex]Make y the subject
Take logarithm to base 2 to both sides
That's
[tex] log_{2}( {2} )^{y} = log_{2}x \\ y log_{2}2 = log_{2}(x) [/tex]But
[tex] log_{2}(2) = 1[/tex][tex]y = log_{2}(x) [/tex]So we have
[tex] {h}^{ - 1} (x) = log_{2}(x) [/tex]Now we can solve the equation
We have
[tex] log_{2}(x) = 0.5[/tex]Convert the logarithm into exponential form using the fact that
[tex] log_{a}(x) = b \: \: \cong \: \: x = {a}^{b} [/tex]So we have
[tex]x = {2}^{0.5} [/tex]But
[tex] {2}^{0.5} = \sqrt{2} [/tex]So we have the final answer as
[tex] \sqrt{2} \: \: or \: \: 1.414[/tex]Hope this helps you

A rectangular parking lot has a length that is 8 yards greater than the width. The area of the parking lot is 560 square yards. Find the length and the width.
Answer: length=28, width=20
Step-by-step explanation:
Let x=width, then length=x+8
x(x+8)=560
x²+8x=560
x²+8x-560=0
(x-20)(x+28)=0
x=20 or x=-28 (rej) since a width can't be negative
20+8=28

2+9x=3(4x+1)-1
Find each solution
Answer:
x = 0
Step-by-step explanation:
Given
2 + 9x = 3(4x + 1) - 1 ← distribute and simplify right side
2 + 9x = 12x + 3 - 1
2 + 9x = 12x + 2 ( subtract 9x from both sides )
2 = 3x + 2 ( subtract 2 from both sides )
0 = 3x ( divide both sides by 3 )
x = 0

8a + 12b = 92 6a – 4b = 4 -- a =? b = ?
Answer:
a = 4 b = 5
Step-by-step explanation:
8a + 12b = 92......eqn 1
6a - 4b = 4......eqn 2
multiply eqn 2 by 3
18a - 12b = 12.....eqn 2
add eqn 1 and 2 to eliminate b
26a = 104
a = 4
put a = 4 into eqn 2
18(4) - 12b = 12
72 - 12b = 12
72 - 12 = 12b
60 = 12b

In buffalo, New York the temperature was -12F in the morning. What will the temperature be if it drops 9F
Answer:
The correct answer is -21 degrees.
Step-by-step explanation:
We know that the original temperature was -12 degrees. If the temperature drops another 9 degrees, this means that it is getting colder or the temperature is getting lower; this lets us know that we should subtract 9 from the original temperature. This is modeled below:
-12 - 9
Now, we simply have to perform the subtraction to get:
-21 degrees
